The MTX-MT75 FSK/ASK transmitter is designed
for applications in the 315 MHz, 433 MHz, or 868 MHz
bands.

The MTX-75 consists of a PICmicro®
microcontroller architecture and a 315/434/868/915 MHz
ASK/FSK RF transmitter. In addition, it features a 4
channel 10-bit analog-to-digital (A/D) converter, one
comparator channel, and 128 bytes of EEPROM memory.
